New York - Roger Federer performed his everyday magic to mow down Tommy Robredo 7-5, 6-2, 6-2 and reach the quarter-finals of the US Open, setting up a rerun of his winning French Open final as the men's top seed started off week two with a solid win. The Swiss world number one, aiming for a record sixth straight trophy at Flushing Meadows, will play against Robin Soderling who advanced 7-5, 3-6, 6-2 when eighth seed Nikolay Davydenko retired with a groin injury.
Federer beat Soderling in June to win his first title at Roland Garros before repeating the victory in the Wimbledon fourth round for an 11-0 record against the Swede.
A US star was born on the women's side with America's newest tennis darling, Melanie Oudin, stretching her fairytale run by knocking out a third straight Russian opponent to move into a breakthrough last-eight spot.
The smiling 17-year-old from Georgia had her family on hand in the cavernous Ashe Stadium during a 1-6, 7-6 (7-2), 6-3 comeback over Nadia Petrova.
Oudin, who announced her presence on the world stage with a Wimbledon fourth-round showing in July, calmly took down the number 13 after losing the opening set and going down a break in the second.
But for the third time in as many matches, the teenager rose to the occasion after losing the first set.
"I kept my belief even when I was down," said Oudin, the youngest US woman to reach an Open quarter-final since Serena Williams a decade ago. "She was all over me, but I kept fighting. I got the break-back in the second set and took it from there. I'm so happy I won.
"She played a lot like my past two opponents, so I had the same kind of game plan going into it. I knew that she was really a tough competitor, and I was going to have to play a good match. That's what I ended up doing."
Kateryna Bondarenko of Ukraine crushed Argentine Gisela Dulko 6-0, 6-0 while Belgian Yanina Wickmayer put out Czech Petra Kitova 4-6, 6- 4, 7-5.
The bubbly Oudin accounted for fourth seed Elena Dementieva in a second-round surprise, stunned 2006 champion Maria Sharapova in the third before completing her Russian hat-trick with Petrova.
She could meet a fourth Russian if 2004 champion Svetlana Kuznetsova beats Dane Caroline Wozniacki.
"I don't think I started well," said the number 70, who broke Petrova's last three service games. "She was serving unbelievable (10 aces), but I stayed with her in the second.
"She gave me a couple of free points, and I gained confidence as it went on. I believed I could do it - and I did. This is really good for American tennis."
